T OOL-HANDLE.

SPECIFICATION forming part of Letters Patent No. 374,063, dated November 29, 1887.

Application filed July 2 2, 1887. Serial No. 244.979. (No model.) I

T0 at whom it may concern.-

Be itknownthat I, WILLIAM H. HAMMOND, a citizen of the United States, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful ImprovementsinTool-Handles, of which the following is a specification.

The object of my invention is to provide a handle which will hold a tool firmly, and yet adapted to be removed from one tool to another with the utmost celerity and ease.

My device is more particularly adapted to hold files and tools of kindred nature which are'provided with shanks for insertion into a handle.

The accompanying drawings illustrate my invention, in which Figure 1 is a view of the handle complete, showing the jaws slightly open for the reception of the shank of a tool. Fig. 2 is-alongitudinal sectional view of the outside of said handle, showing the arrangement and operation of thejaws and the inside parts and devices of the handle. Fig. 3 is a plan viewof the top of the collar 1).

In Fig. 2, a represents the body part of the handle, which may be composed of wood or other suitable material. The body a is provided with the metallic end eand the frictioncollar 0. The metallic end 6 is perforated and screw-threaded for the reception of thescrewthreaded stand 9. The jaws d d are pivoted in the end of the stand 9 atf, and are provided with ribs n on their sides, as shown in Fig. 2.

Z is a collar having a shoulder which is screwed or pinned into the metallic end 6. The collar m, provided with the legs h, swivels under the shoulder of the collar or plug Z. c

' when thejaws are caused to advance out of the handle. Thelegs h h extend through the holes t' t in the collar 1), and are there riveted.

The operation of the device is as follows: '50 The several parts of the handle being in position, as shown in Fig. 2, the collar 1) is revolved to the left, which action, by means of the screw-threaded stand 9 working in the end 0, throws the jaws d d forward and opens them. The shank of the file or other tool which it is desired to hold is now placed between the jaws and the collar is turned to the right, thus drawing thejaws d d back into the handle and causing them to clamp the shank of the tool firmly. It will be seen that when the collar 1) is turned the jaws d d necessarily turn with it, thereby causing thescrew-threaded stand 9 to advance and recede, as the case may be, and at the same time cause the jaws d d, which are pivoted in said stand, to approach or recede from each other. v

Having thus described my invention, what I claiin,and desire to secure by Letters Patent,

A tool-handle consisting of the shell a, collar b, provided with openings 8 s and points 1", end e, jaws (Z d, having ribs .n, pivoted at their inner ends in the stand 9, said stand screwthreaded and working in end 6, shouldered plug Z, secured in the end 6, as described. and collar m, provided with legs h to hold the several parts together, all as shown and described.
